BOTTLE fOR CONTAINING LIQUIDS 0R GASES UNDER HIGH PRESSURE.

SPECIFICATION formingpart of Letters Patent No. 660,326, dated October23, 1900.

Application filed August 31, 1899. Serial No. 729,066. (No model.)

To all whom it may concern.-

Be it known that I, GRAHAM CLARKE, a citizen of the United States, and aresident of Cleveland, county of Ouyahoga, and State of Ohio, haveinvented a new and useful Improvement in Bottles for Containing Liquidsor Gases Under High Pressure, of which the following is a specification,the principle of the invention being herein explained and the best modein which I have contemplated applying that principle so as todistinguish it from other inventions.

My invention relates to improvements in means for containing liquids orgases under high pressure and for controlling the How of same, theobject being to secure an economically -const-ructed receptacle forcontaining such liquids or gases provided with a valve absolutelycontrolling the flow of same without the use of packing, whereby allpossible loss of the contents through leakage is prevented.

Said invention consists of means hereinafter fully described.

The annexed drawings and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting but one of various mechanical forms in whichthe principleof the invention may be used.

In said annexed drawings,'Figure I represents a side elevation of theupper portion of a liquid or gas containing bottle embodying myinvention. Fig. II represents a vertical axial cross-section of same.

The invention consists of a metal (usually steel) bottle A, which isdrawn so as to form an integral neck a, in which is transversely locatedan integral wall at, having a central axial tluid-opening a said neckforming a support or body portion for a closure-valve ofimprovedconstruction. Said neck is bored and counterbored so as to form ashoulder a The center of the bottom. of the counter-bore is bored toreceive a hard-rubber valve-seat I), having a flat upper surface and anaxiallylocated duct or fluid-opening b, communicating and registeringwith the duct a The upper surface of said seat is raised and issubstantially in the same plane with the upper surface of shoulder athereby forming an annular space a between said shoulder and valve-seat.Resting upon said shoulder is an imperforate diaphragm d, whose rim issecured upon the shoulder a by means of a jam-nut 6, having threadedengagement with the neck of the bottle, as shown. Said nut is formedwith an inner axial bore 6 and pro= vided with a set-screw f,communicating with said bore 6, Said screw is formed with an inner axialbore f, as shown. A plunger g, formed with a teat g, rests upon themiddle of the diaphragm, the teat projecting into the screw-bore. Theplunger being, as above described, intermediate with respect to thescrewfand the diaphragm, it is seen that the depression of said nut willcause the inner end of the bore f to engage the teat and press thediaphragm down upon the valve-seat and securely close the openingtherein. An outlet-duct a is formed in the body of the neck andcommunicates with the annular space a On the release of the plunger bythe outward movement of the screw the pressure of gas or liquid in thebottle raises the diaphragm and permits the escape of'the contents ofthe bottle as desired. The diameter of the teat and body of the plungerare made such as to permitof rotative movement of the plunger in thenuts f and 6, whereby the rotation of the plunger upon the diaphragm isprevented and said diaphragm preserved from injury.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismhereinidisclosed, provided the means covered by the following claim heem ployed.

I therefore particularly point out and distinctly claim as my inventionThe combination of the bottle A formed with the integral transverse walla formed with a central opening, the valve-seat 1) formed with. theopening I) registering with said central opening, the diaphragm dsupported by the shoulder a formed in the bottle-neck, the.

jam-nut e for securing said diaphragm upon said shoulder and formed withthe bore 6', the set-screwfcommunicating with said bore formed with thebore f, and the plunger g located in bore 9 and formed with the teat gprojectinginto bore f, said neck formed with the opening a communicatingwith the annuler space intermediate of said raised valveseat and saidshoulder, substantially as set forth. 1o

Signed by me this 28th day of August, 1899.
